In case of highly monolith NPs, this [[tau].sub.b] tends toward bulk lifetime of substance, while in more loose aggregates of many NPs, it is higher reflecting their reduced compactness.
The open circuit voltage increased about 16 mV at lower temperature, this is because the low temperature (800[degrees]C) passivation has higher bulk lifetime than the high temperature (1050[degrees]C) passivation.

where W is the thickness of the wafer and [[tau].sub.bulk] represents the bulk lifetime of the wafer, which is a combined result of Auger, radiative, and Shockley-Read-Hall recombination.
The effective lifetime ([[tau].sub.eff]) is a combination of bulk lifetime ([[tau].sub.bulk]) and surface lifetime ([[tau].sub.sur]) as follows:
